Editing `ExecStart=` with `systemctl edit` did
not work for me. Running
`systemctl restart thermald.service` afterwards
was giving errors every time with reason "Unit
thermald.service has a bad unit file setting".
By running `systemctl status thermald.service`,
I was reading this error:
redis.service has more than one ExecStart=
setting, which is only allowed for
Type=oneshot services. Refusing.
By looking through the Internet for answers,
I found a suggestion from a user saying that
"The `ExecStart=` line cannot be modified with
`systemctl edit`"
(https://unix.stackexchange.com/questions/409354).
What worked was replacing the thermald.service file
directly to `/etc/systemd/system/` and
`/usr/lib/systemd/system` worked, as suggested
in the README.md present in the folder containing
example configurations for Surface Pro 5 from
this repository.
